GEORGE F. ROBINSON, OF NEW YORK, N. Y.

FEED-TROUGH.

SPECIFICATION forming part of Letters Patent No. 476,071, dated May 31,1892.

Application filed May 21, 1891. Serial No. 393,616. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. ROBINSON, a citizen of the United States,residing at New York, in the countyand State of New York, have inventednew and useful Improvements in Stock-Feeders, of which the following isa specification.

This invention relates to an improvement in feedersfor live stock; andthe invention consists in the details of construction set forth in thefollowing specification and claim, and illustrated in the annexeddrawings, in which- Figure 1 shows the feeder closed. Fig. 2 shows thefeeder open. Fig. 3 is an edge of a chute. Y

The chutes A (one or more) are placed over troughs or mangers B. Thevalves or lids O are each rigidly secured to the lower end of a levercomprising two arms D and E, fulcrumed by a pivot F on the chute A insuch manner that when the lever is oscillated the valve swings in thearc of a circle to open or close the mouth or lower end of the chute.The lever-arms E are connected by a rod or cord G with any suitablewell-known mechanism (not shown)-as, for example, a magnet-so that whenfeeding-time arrives a clock (not shown) releases or devitalizes themagnet, allowing the lids O to swing or fall open, and all the troughs Bare at the same time sup plied with the proper amount of feed, afterwhich the magnet or mechanism again comes into play and the cord or rodG draws the lids O shut. When the lids or valves 0 are in their closedposition, the valve-supporting arm D hangs substantially vertical, sothat theweight of the valve and of the feed thereon is supported orborne by the fulcrum or pivot F. Very little force is thus required toactuate the lever for opening the valve, so that the power to be exertedby the rod or cord G on the actuating-arm E of the lever need not belarge. As the lid or cover O swings up against the bottom of the chuteto close the latter, said lid is able to readily close the chute withoutcrushing any of the feed,which crushing might occur in case the lid hada sliding instead of a swinging movement. The chute has a flange H atits mouth, said flange being inclined toward the valve, so that the feedcannot rush laterally off the valve and shoot beyond the trough, but thefeed is compelled to descend in a substantially vertical direction, soas to enter the trough.

What I claim as new, and desire to secure by Letters Patent, is-

A-stock-feeder consisting of a chute and an oscillating lever pivotedintermediate its extremities and having a valve 0 rigidly attached tothe lower extremity of the lever and swinging therewith in the arc of acircle when the lever is oscillated, said lower extremity of the leverstanding, approximately, in a perpendicular position when the valvecloses the discharge-mouth of the chute, and the chute being providedwitha stop-flange II, inclined toward the valve to prevent lateraldiversion of the feed and compel it to flow in a vertical directionbetween such stop-flange and the valve, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

GEORGE F. ROBINSON.
